Once a tree has been infected by the psyllid that carries and transfers the huanglongbing (HLB) bacteria to the tree there has been no alternative but to quarantine the infected area and destroy the tree. To complicate the issue further, the disease can lie dormant and be difficult to detect as the infection spreads from tree to tree.
Efforts to control the psyllid through pesticides have been ineffective and while quarantines have helped raise awareness and slowed some of the spread, a viable weapon to combat this invasive pest has been unavailable until recently.
Mark Hoddle, director at the Center for Invasive Species Research at UC Riverside, has been experimenting with a tiny parasitic wasp, Tamarixia radiata, that feeds on and kills the psyllid. After a series of tightly controlled and successful tests, the wasps have been released on infected sites and have been effective in reducing the psyllid population. There is no danger to pets or humans and the release program has been approved by the Department of Agriculture.

The website explores chemical injury, nutritional disorders, physical and physiological disorders found in the field and during research. The team collaborates and shares information about these issues and discuss methods for dealing with them.
The website is presented in English and in Spanish and is accompanied by large photos that focus on the problem areas.

Spider mites are a major recurring pest of strawberry. If left untreated, these pests will infest fields, decrease yield and eventually kill your plants. Several methods are available to help control spider mites on strawberry including biological control (i.e., predatory mites) and miticides. Watch this video to learn more about spider mites in strawberry and their control:
Anna Howell, UC Ventura County Cooperative Entension's staff researcher and entomologist, will join UC advisors and California agricultural experts for a "Mite Pest Management in Strawberry" meeting in Salinas, California.
Presentations include management of destructive mites, chemical and alternative options for control and identification of mites.
Speakers will also focus on the two-spotted spider mite and Lewis Mite. Anna Howell has been part of a research project studying the Lewis Mite which has been known to cause damage in strawberry and raspberry crops. The two-spotted spider mite causes damage to strawberry in coastal areas.
